Tariffs stay hot even as oil cools

Oil prices cooled abruptly and markets exhaled. But the relief is partial: the shock is migrating from barrels to borders. The macro risk now is not just energy — it’s unpredictable trade policy with sticky inflation effects.

Thesis: the diplomatic de‑escalation knocked out the war premium in crude, but tariffs and regulatory friction remain. With central banks still shrinking balance sheets, the mix is clear: less immediate energy fear, more structural pressure on costs and supply chains.

1) Oil cooled, but the cycle didn’t reset

On March 10, crude corrected sharply after signals of de‑escalation in the Middle East. FinancialContent reports WTI sliding toward $88–$89 and Brent around ~$92, far from the ~$120 levels feared days earlier. The narrative flipped in hours: from Hormuz disruption risk to diplomatic relief. Good for inflation — but the volatility is now visible and will linger.

2) The U.S. closed a legal front — and opened a trade one

The U.S. Supreme Court ruled broad IEEPA tariffs unlawful, but that didn’t mean trade peace. C.H. Robinson notes immediate 10% Section 122 tariffs for 150 days, and the continued suspension of de minimis for all countries. Net effect: higher entry costs and a messier policy environment just as firms try to stabilize pricing.

3) The ECB keeps draining liquidity

The Eurosystem’s weekly balance sheet shows continued asset runoff. In the March 6 consolidated statement, securities held for monetary policy fall by ~€22.4bn and total assets drop ~€50.3bn week‑over‑week. It’s not a hawkish pivot, but it is a signal: liquidity is still being pulled back, which thins the buffer against cost shocks.

Implications (30–90 days)

1. Border costs beat energy costs. If oil stabilizes but tariffs rise, the “tax” shifts from energy to trade. That hits physical goods first, not services.

2. More margin volatility, less pricing clarity. Temporary tariffs + de minimis suspension + open litigation make final prices less predictable. Firms will either raise prices or shorten contracts.

3. Europe stays exposed on two fronts. Lower energy inflation helps, but global trade tightening plus an ECB still running QT weighs on growth — especially in manufacturing and exports.

Close

Energy calm is not a macro reset. Risk is relocating: from a volatile barrel to a more expensive, less stable border. If companies don’t adjust sourcing and pricing strategy, the shock won’t come from oil — it’ll come from customs.
